AN aeroplane wing and fuselage may be treated from an analytic standpoint as two elastic beams, rigidly connected. In the present note the equations for the natural frequency, derived on the basis of Rayleigh's principle and Ritz's method, are extended to the case of free vibration of a set composed of two such beams with a number of concentrated loads

A composite (or hybrid) beam is in the following defined as a beam with cross section made up of a layer of segments with different thickness and material properties, as illustrated in Fig. 7.1. It is taken for granted that layers of material segments are parallel to the y axis and that the cross section is symmetric about the z axis.

The beam elements discussed so far consist of homogeneous, isotropic material. Within this chapter a finite element formulation for a special material type — composite materials — will be introduced. On the basis of plane layers the behavior for the one-dimensional situation on the beam will be developed.

A three-dimensional (3D) beam, also called a rod, is a member that carries axial, flexural (shear and bending) and torsion force resultants. Structures containing 3D beams are found in frames of buildings and industrial constructions, arches, stiffened shells, structural parts in land transport vehicles, fusselages of airplanes and spacecrafts, ships ...

The problem of the torsion of a composite beam made up with several orthotropic materials has been formulated using a warping function. By using a finite difference method or a boundary integral method in the case of transversely orthotropic phases we can calculate torsion stiffness, locate the shear stresses and shear center.

Beams are autonomous or secondary load bearing members of many structures. They are used extensively in the formation of linkages, shafts and frames and as reinforcements on plate and shell panels. They are also used in robotics and high speed machinery.

It is now common practice to use cold‐formed steel decks consisting of profiled sheets both as permanent formwork for the support of the soffits of reinforced concrete slabs and also as part of the tension steel in the composite profiled slab that is formed after the concrete has hardened.
